Very happy with the mattress we got! Very good quality. Great warranty. I really liked that Vladimir showed me the inside of the mattress as well. It’s pretty cool because you see and can touch what’s inside. We were able to lay down on the mattress and find what we like before they built it for us. They also delivered it to us. And not only they can do regular mattresses but they also can do custom size mattresses. I got 2 mattresses for my camper. Which is pretty nice. I am happy that we have a local mattress shop like that here in Springfield area.
View on GoogleWhat a great experience buying a mattress! We went to the showroom and picked out all the materials we wanted, and spent as much time as we needed exploring the options. The sales guy was zero pressure and was happy to help. We ended up with a custom mattress for much less than what you’d pay from a big box store. The customer service was fantastic from start to finish. They were able to deliver to our place and even hauled it upstairs. Love this company and everything they’re up to. Build quality seems very high and we are very happy with the product. We will be back!

View on GoogleBought 2 full mattress for my kids bunk bed from Sigma and had to return to purchase a new one for myself. The quality is beyond anything I’ve slept on before. Vladimir was very friendly, knowledgeable, and built us exactly what we wanted. Loved learning about the manufacturing process and the custom selection for materials and firmness. Will definitely recommend to family and friends.
